Greek philosophy is as brilliant as every other creation of the Greek intellect. The line of thinkers which that little nation produced in three centuries has no parallel in the history of thought, and every conceivable variety or cast of speculation made its appearance. But Greek thought became distorted by religion. It turned away from science to “spiritual truths”. It has shown for all time how futile and mischievous is that high sounding appeal for us to turn from science to “spiritual truths”.
Skepticism, by the general philosophical definition, is the point of view that confronts every philosophical thesis (many times, even the non-philosophical) with rational thought and doubtful criticism. The word derives from the Greek verb «σκέπτομαι (sképtomè) = to think or to think about» whose action causes thinking and thought (based on logic, at least at the advanced level) which, in the context of skepticism is aimed toward criticism and dispute. Finally, skepticism concludes with the acceptance or rejection of a position and also leads to the classification and separation of different positions.
It all began, as usual, with the Greeks. The ancient Greeks were the first civilized people to use their reason to think systematically about the world around them. The Greeks were the first philosophers (philosophia — lovers of wisdom), the first people to think deeply and to figure out how to attain and verify knowledge about the world.
The History of Yoga has a lot to do with the present times. The earliest Yoga started some 5000 years ago since human civilization has begun. The scholars have believed that Yoga was originated out of Stone Age Shamanism. This is because there were some cultural similarities between Mehrgarh which was a Neolithic settlement and the Modern Hinduism. The shamanistic culture of Mergarh was in fact influenced by Hindu ideals, symbols and rituals of the present. The ancient shamanism and early Yoga had so much similarity for the reason both wanted to go beyond the human condition.
